Slope formula;
m = y2 - y1/ x2 - x1                     point(x, y) = (4, 1), (7, -2)
 
m = -2 - 1/ 7 - 4
m = -3/3
m = -1

the slope is -1.

hope this helps, God bless!

Red and grey bricks were used to build a decorative wall. The number of red bricks and grey bricks was 5/2. There were 140 brick
ozzi

Answer:

100 red bricks

Step-by-step explanation:

Let's say red bricks is equal to 5x

Gray bricks is equal to 2x

We have an equation

2x + 5x = 140

= 7x = 140

Divide through by 7 to get the value of x

X = 140/7

X = 20

Red bricks = 5(x)

= 5(20)

= 100

Gray bricks = 2(x)

= 2(20)

= 40

Therefore in conclusion the number of red bricks is 100.
